The Founder’s Logic: The M-as-XL Paradigm
To assist in your selection, our Founder provides a personal reference for the intended REALLY COOL® silhouette:
" To achieve the intended architectural drape and the signature 420 GSM " shell " effect, I wear a Size M. In brands like Timberland, Levi’s, or Calvin Klein, I am a standard US XL. Choosing Size M in REALLY COOL® ensures the boxy form remains structural even in motion. Stepping up to an XL in our range is reserved strictly for avant-garde, high-volume editorial silhouettes."
Precision Measurement Protocol
To ensure the perfect fit, follow these technical steps:
-
Chest (Architectural Width): Lay your best-fitting heavyweight tee flat. Measure armpit to armpit.
-
Length (Vertical Presence): Measure from the Highest Point of Shoulder (HPS) straight to the hem.
-
Shoulder (The Drop): Measure seam to seam. Note: Our Dropped Shoulder is engineered to be wider than mass-market standards.


International Conversion & Anchor Guide
Use the chart below to determine your REALLY COOL® size based on your usual size in brands like Timberland, Levi's, and Calvin Klein.

" Urban Armor "
Our Design Philosophy
REALLY COOL® garments are engineered with a signature Extreme Oversized / Boxy Silhouette. Unlike mass-market apparel, our pieces are designed as an “Architectural Shell”, a structured layer that stands away from the body to provide a powerful, high-presence silhouette.
Our design logic centers on Structural Integrity:
-
Boxy Construction: An identical width from chest to hem, ensuring the garment retains its geometric form.
-
Dropped Shoulder Engineering: Strategically lowered seams to provide a broad-shouldered aesthetic without compromising range of motion.
-
420 GSM Heavy-Knit: High-density fabric selection that emphasizes structure over drape, creating the true "Urban Armor" effect.
" Recalibrated Scale "
Critical Fit Note
To achieve the intended runway aesthetic, REALLY COOL® has recalibrated traditional sizing standards. Our sizing operates on a shifted scale to accommodate the extreme volume of the "Urban Armor" cut.
IMPORTANT: OUR SIZE M IS PHYSICALLY EQUIVALENT TO A STANDARD U.S. / EUROPEAN XL.
Trust the Engineering, Not the Label.
-
Intended Fit: If you typically wear a Standard US/EU Large or XL, our Size M will provide the precise oversized aesthetic as envisioned by the designer.
-
Downsizing: For a more conventional "Relaxed Fit," we recommend selecting one to two sizes smaller than your usual preference in legacy brands.

For Wholesale Partners
REALLY COOL® sizing is calibrated to be 2 sizes larger than Timberland standards to ensure the Urban Armor aesthetic.
